memory handling in vizard

[Jeff]

If the number of primitives or drawables is high, then the frame rate will drop when they're in view. How many polygons for this model and what kind of graphics card do you have? Do you see the frame rate drop as the object moves into view and does it stay at that lower rate?

in the workstation is a quadro 3800, the three models have a polycout of about 2,5 million polygons. we already decreased the total number for the final scene but i still have a little interruption in the viewport.

as long as you don't take a look away from the model the framerate is stable, but if it moves back in view this short stuttering is happening. is there in the code a kind of flag that i can set that vizard keeps all models in cache, even if the view moves away from the model?

No, there is no command for that. You might try disabling nVidia's power saving mode. Go to Manage 3D settings in the nVidia control panel and look to see if there is a power management setting. If there is one make sure it's set to something like "maximum performance" rather than "adaptive".
